Etymology: Engraulicypris: Greek, eggraulis, -eos = anchovy + Greek, kypris = the name of Aphrodite, proceeding from Kypris, (Cyprus), Greek, kyprinos = carp (Ref. 45335); howesi: This species is anmed in honour of Gordon John Howes (1938-2013), whose studies of the osteology of the Danioninae laid the foundations of their modern classification; the epithet is a genitive noun (Ref. 116496).
Eponymy: Dr Gordon John ‘Gordi’ Howes (1938–2013) was an ichthyologist and fish systematist at the BMNH, which he joined as a scientific assistant (1968). [...] (Ref. 128868), visit book page.

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 8 - 10; Anale stekels: 0; Anale zachte stralen: 16 - 18; Wervels: 38 - 40. Diagnosis: Anal fin extending over three quarters of length of caudal peduncle; caudal peduncle short; operculum entirely, not partially, shiny; body midline silver, not black; iris dark to light grey, not white; head with tubercles along lower jaw and lower head in breeding males; snout rounded; pelvic fin melanophores absent (Ref. 116496).
This species appear to favour turbid, rocky, river regions where they can gather in pockets of recirculating currents (Ref. 116496). They feed on drifting invertebrate larvae and adults and plankton (Ref. 116496).
